i have been googling the solution from the last two days and still didn't got the solution.i think it has something to be done with the permissions.let me post you my file permissions for /var/mail/folders/user1

drwxr-xr-x 2 root root 4096 Feb 13 13:56 /var/mail/folders/

-rwxrwxr-x 1 root root 1458 Feb 13 13:56 user1

if you find any loophole with this.then please let me know as well...this thing had screwed up my head..
